Dear CAT12 experts, I am working on a longitudinal VBM study, using the longitudinal segment module of CAT12 for preprocessing, but I have a few questions and would appreciate your help
1. Is it must to perform AC-PC reorient before splitting?
2. Our data are from Asian people, should affine regularization use European template or East Asian template
3. Should Crop neck nii data be used, or the original nii data be used,should I use dcm2nii or dcm2niix to convert DICOM.
4. If there are three time points and two groups, and want to analyze time and the interaction effect of time and group, how should the contrast matrix of flexible design be designed?
5. The results of different CAT12 versions are different. Is the result of CAT12.8 more accurate than that of CAT12.7 and CAT12.6?
6. Does the longitudinal data have to be preprocessed by longitudinal segment module, is it possible to use ordinary segment module for preprocessing?
Looking forward to your help, thank you very much
